Googles older Pixels wont get the Pixel 4s dual exposure and Live HDR+ features

Google introduced a lot of cool new Pixel camera features at last weeks event. Some of them, like astrophotography mode, will be coming to older Pixel devices. But two will apparently remain exclusive to the brand-new Pixel 4 and 4 XL: dual exposure controls, which let you adjust highlights and shadows right from your viewfinder, and Live HDR+, which gives you a live preview of what your photo will look like with Googles HDR processing applied.
